Jonathan Miller, President and CEO of Miller Samuel Inc., says the explosion of housing market data on social media has created widespread confusion and made source credibility as crucial as the data itself. As more information circulates online, Miller warns that the quality and reliability of that information have declined, making it harder for both consumers and professionals to make informed decisions.

“There’s so much volatility and misinformation floating around right now that there seems to be more of a premium being placed on neutrality and detailed information and data,” Miller says. His firm, whose market analysis is used by the Federal Reserve and other government agencies, gives him direct insight into how institutional investors are reacting to what he describes as an information credibility crisis.

Miller’s warning comes at a time when housing market commentary is spreading rapidly across digital platforms, often without transparent sourcing or methodological rigor. He says the problem has become severe enough that he now makes source verification a central part of his teaching at Columbia University’s graduate program.

The Transparency Paradox

While the increased availability of housing data is generally seen as a benefit for market transparency, Miller says it has also created new risks. “With social media and websites and much greater transparency of housing data than ever before, I think it’s essential for investors to double down on really paying attention to who the source is for the information,” he says.

Miller notes that social media is filled with broad statements about housing that lack proper sourcing or analytical support. He emphasizes to his students and clients that the credibility of the source is as important as the data itself. “Think of the source of the information as equally important to the information itself,” he says. To illustrate, Miller offers a straightforward rule: “If you see a chart without a source on it, it’s a lie, or there’s something about it that’s being hidden that you want to ignore.”

He says this issue comes up daily in his work with institutional investors and analysts. “I see this every day, so I just encourage people to be more careful about sources,” Miller says. “I think it’s really critical in this period of volatility.”

Institutional Investors Adapt

As misinformation becomes more common, Miller observes that institutional investors are adapting by placing greater emphasis on source verification and methodological transparency. “There’s so much volatility and misinformation floating around right now that there seems to be more of a premium being placed on neutrality and detailed information and data,” he says.

This new focus has given firms a competitive edge that can demonstrate analytical rigor and neutrality. Miller says Miller Samuel Inc. positions itself as a “neutral market observer,” providing unbiased data rather than marketing-driven reports. “We’re neutral market observers. We don’t really care about your problems. We really want to provide a neutral benchmark for users of our report information to make informed decisions.”

He contrasts this with much of the industry, where market studies are often thinly veiled marketing materials. “When a broker or a company or an individual produces a market study, most of them end up being brochures with numbers on them, highlighting the expertise or experience of the author,” Miller says. “We put that in the back seat.”

Miller Samuel’s Douglas Elliman Report series is designed for a broad audience, from consumers and businesses to government agencies and academics. This wide reach, Miller says, requires strict methodological transparency and transparent sourcing.

Recognition from the Federal Reserve

Miller first realized his firm’s neutral approach was gaining traction with institutional clients after an unexpected email from the Federal Reserve. “I got an email from the Fed, the Federal Reserve, complaining because I didn’t have my latest research on our website,” Miller recalls. “And I said, Oh, we’re on to something.”

Today, Miller Samuel’s research is used by numerous federal agencies and regularly cited in the media. Miller attributes this adoption to a straightforward approach: “We just call it as we see it, good or bad, and let other people rely on that so they don’t have to say, Oh, they’re always on the positive side or the negative side.”

This neutral positioning is especially valuable in volatile markets, when conflicting narratives multiply. Miller says institutional decision-makers increasingly look for sources with consistent methodology and transparent attribution—qualities that are becoming harder to find as commentary proliferates online.

Industry-Wide Challenge

Miller’s concerns about misinformation extend beyond social media to the broader industry’s approach to market intelligence. He argues the main challenge is not just outright falsehoods but a lack of analytical rigor and context in much of the commentary circulating today.

His firm’s approach centers on providing detailed information with transparent sourcing and methodology, enabling users to make informed decisions rather than relying on vague generalizations. Miller’s consulting work for Wall Street analysts and investor groups gives him ongoing insight into how institutional capital allocators are responding to this environment. “I’m brought in to speak to investors. I do consulting for Wall Street analysts,” Miller says. “That’s very helpful, because I’m getting their perspective or insights.”

These interactions confirm that sophisticated investors are prioritizing source credibility as a risk management strategy. In a market where data is plentiful but quality varies, Miller says the ability to identify reliable sources is as crucial as interpreting the data itself.

Miller Samuel’s Approach

Miller Samuel Inc. has built its business around serving clients who demand source credibility and analytical neutrality. The firm produces the Douglas Elliman Report series, covering multiple markets and providing specialized appraisal services for complex cases.

“We do a lot of consulting,” Miller says. “I’m also brought in to speak to investors. I do consulting for Wall Street analysts.” This ongoing engagement, he explains, helps the firm tailor its services to meet the needs of different client groups.

The firm’s research is used by government agencies, businesses, and consumers, all of whom require consistent methodology and transparent sourcing. Whether Miller’s focus on source credibility becomes standard practice across the broader industry may depend on how quickly institutional investors recognize misinformation as a significant risk in their decision-making.

As the volume of housing market commentary grows, Miller’s message is clear: in today’s environment, knowing where the data comes from is as important as the data itself. For investors and analysts navigating a volatile market, source credibility is no longer optional—it is essential.
